Details

Self-support currently waits for 5 seconds after sessionstore-windows-restored before running its delayed initialization code. There's no guarantee that this is a good time for it to run, though, so it should really wait for an idle callback instead.

We're planning to remove self-support in favour of SHIELD / normandy. Not sure how useful it is to invest in it much in the meantime. Mike, can you clarify what the latest schedule for those plans looks like?

Just waiting for an idle callback after the timer expires is a pretty minor investment, which might be a non-trivial startup perf win...
We shipped the Shield system add-on to release today at 100%. The system add-on disables self-support. so this shouldn't affect any more users.

Also, I think we're ready to remove self-support now, since it's replacement has shipped.

For additional context, this was WONTFIX'd because the self-support system is going away.
